Description

Field of the invention

The present disclosure relates to an uninterruptable power supply, UPS, information communication system and a corresponding information communication method.

Technical background

In industrial environments, uninterruptable power supplies, UPS, are frequently used to provide safety against loss of power. Generally, the UPS are monitored by external devices, so called information collectors, that collect UPS information, which comprise status information of the UPS, and process the respective UPS information. This includes for example monitoring a maintenance status or loading states of the UPS. However, often UPS of different manufacturers are used in the industrial environment. Usually, an information collector of a first is only able to collect and process UPS information from its own UPS. Thus, the information collector of the first is not able to include the UPS of other manufacturers, which limits the functional possibilities of the information collector.
Thus, there is a need for an improved UPS information communication system that allows an information collector of a first to collect and process UPS information of all UPS in the information communication system independent from their manufacturer.

Summary

According to an aspect of the invention, an information communication system comprises: A communication network, configured to exchange uninterruptable power supply, UPS, information. A UPS, connected to the communication network, wherein the UPS is configured to exchange UPS information to the communication network. An information collector, wherein the information collector is configured to collect and process the UPS information. The information collector has no direct access to the UPS information. The information communication system comprises an information aggregator that is connected to the communication network and is configured to poll the UPS information from the UPS, to generate collector information using the polled UPS information and to send the collector information to the information collector.
In other words, the UPS provides UPS information to the information collector over the communication network with the help of the information aggregator.
The term "polling", as used herein, relates to a procedure by which a device, in this case the information aggregator accesses a network, in this case the internal network, calls another device, in this case the UPS , and downloads information, in this case the UPS information, stored in the device. In other words, polling comprises a request, in particular a cyclic request, for information.
The term "direct access", as used herein, comprises the information collector not having access rights to the UPS, the information collector not knowing how to poll the UPS information from the UPS, the UPS is not sending information to the information collector, and/or the information collector not being able to interpret the UPS information polled from the UPS, in particular the UPS information not being in a format that is processable by the information collector.
For example, the UPS is of another brand as the information collector leading to the information collector not having direct access to the UPS.
The term "information", as used herein, is also referred to as "data".
For example, the UPS information is provided by the UPS in form of a ZIP file.
The information aggregator is not a gateway between the UPS and the connection to the information collector. It is rather an active device added to the communication network of UPSs, addressing UPSs autonomously and sending out the information to the information collector. The information aggregator can determine the collector information, in other words, when a UPS is not reachable anymore in the local network, or when it gets rebooted, polling statistics based on the polled UPS information. The collector information are communicated to the information collector. The collector information is not collected from any other device in the network.
